EX-TENSIBLE SPRING-ROLLER.

Specification of Letters Patent.

Patented Feb. 27,1906.4

Application le'd November 29, 1904. Serial No. 234,790.

A of which the vfollowing is a specification'.

This invention is applicable generally to spring-rollers used in thearts `for a4 variety of purposes-such, for instance, as-anl adjustable su port fora shade, a curtain, a cover, or other fiexible article-and is especially designed to furnish a spring-roller construction enabling the length of the roller to be readily increased or diminished to suit the requirements of any particular conditions.

The present roller construction comprises a pair of telescoping members, one an outer or exterior tubular member and the other an inner member encircled by a coiled or helical spring, which is placed under tension when one member is rotated relatively of the other in the usual manner.

In the drawings accompanyin the present specification, Figure 1 is a side e evation of a spring-roller embodying my present improvements, part being broken away to show the outer and the inner telescopmg members. Fig. 2 is an end elevation. Fig. 3 is an enlarged elevational view of the inner telescoping member removed from its position within the exterior member and shows the coiled spring which encircles it and likewise the sleeve through which it is adapted to slide.

Reference characters are relatively alike throughout the drawings.

The exterior member of the roller constitutes the means to which the edge of the curtain, iexible cover, &c., may be secured and upon which and from which this iexible element is wound upand unwound, respectively. This member is of telescopic construction, comprising a tube 2 and fitted to slide lengthwise therewithin a tube 2. While the two may be readily moved lengthwise of each other, their relative rotation is prevented by some suitable means, here consisting of a longitudinal depressed portion 2 of the tube 2, which lits within a counterpart channel 2a in the exterior of the tube 2. Within the exterior telescoping member is an inner member of similar construction, the parts ofwhiGh are likewise longitudinally movable but rota,-` rily relatively immovable. construction of this inner member comprises a tube, fitting within atube 4 and having wisebetweenthe walls of a slot 4, inthe latter tube.

SecuredY within one end of theinner teleis a similar stud 5". These studs pro'ect beyond the respective end plates 6 6 of t e exterior telescoping member, and while they are as tolpreclude their axial movement relatively to the plates in which they are mounted. One end of the coiled or helical spring 7 is relatively fixed (so far at least as rotary movement is concerned) to one part of the inner member, and the othr'end thereof to a part of the outer member, althou hthe meanswhereby this securing is efecte is not such as to prevent the free and ready telescoping of theparts. Such results are accomplished by the construction illustrated, in which one end ofthe spring is caught into a sleeve 8, slidably mountedY upon the tubev 4 and secured to one of the outer telescoping tubes, as by indenting the latter, (see 9,) in the event that the sleeve is made of wood and the tube of metal. The other end of the coiled spring is hooked over (see 10) and enters the slot 4. Itis evident from this construction that the spring may readily perform its function throughoutthe possible telescoping adjustment of the parts.

The projecting ends of either one or both of the studs 5 5 may have the usual slot 1l for engaging with the usual slotted supportingbracket, (not shown,) and while nol holdingdogs are shown for retaining the telescoping members in the position to which they ma be rotarily adjusted it is obvious that these may be provided when desired, since their construction and modes of operation are well known.

Preferably the shade, cover, &c., 12, is removably secured to the exterior member.

loop 12 in the cover end and the latter then laid in the vdepressed portion 2 and channel The illustratedv a projecting pin 3', adapted toslide length-f scoping member is a stud or .projectingpin l5 andextending from'the opposite end thereof For instance, a rod 13 may be run through a j ournaled in such end plates they are so formed i IOO 2a of the exterior member, whereupon if the cover is wrapped one or more times around the latter it will be securely held in place.

I claim as new and as my invention- 1. A telescoping spring-roller comprising in combination, yan exterior telescoping member, an inner telescoping member provided with a longitudinal slot, a sleeve slidably mounted on the inner member and secured to the exterior member, and a spring one of whose ends is secured to said sleeve and whose other end enters said slot.

2. In a telescoping spring-roller,` the combination of a pair of telescoping tubes constituting an exterior member, a pair of telescoping tubes constituting an inner member, studs extending from the inner member and upon which the exterior member is mounted, and aspring interposed between said members.

3. In a telescoping spring-roller, the combination of a pair loi telescoping tubes constituting an exterior member, plates at the ends of said member, a pairof telescoping tubes constituting an inner member, slotted studs extending from the inner 'member and upon which said plates are mounted, and a spring interposed between said members.

4. In a telescoping spring-roller, the combination of a pair of telescoping tubes constituting an exterior member whose parts are relatively immovable radially, a similar telescoping inner member which is provided with a longitudinal slot, studs extending Jfrom the inner member and upon which the exterior member is rotatably mounted, a sleeve slidably mounted upon the inner member and which is secured to the exterior member, and a spring one of whose ends is secured to said sleeve and whose opposite end enters said slot.

In testimony whereof I have signed my name to this application in the presence of two subscribing witnesses.
